Challenge Seamless Latex Presta 47.5mm Inner Tube

Seamless Latex Presta 47.5mm Inner Tube The distinctive Challenge Seamless Latex Presta 47.5mm Inner Tube offers significant advantages; saving more than 3 watts per wheel compared to a butyl inner tube; as confirmed by testing conducted in Germany; Finland; Belgium; the Netherlands; the UK; and the USA. This lighter; softer; and more supple tube reduces rolling resistance; enhancing comfort; traction; and cornering ability. Additionally; puncture protection is greatly enhanced due to latex’s ability to expand 7 to 8 times its original size; compared to butyl’s 1.5x expansion. Latex’s flexibility allows it to wrap around protruding objects; often preventing punctures altogether. Unlike stiffer butyl tubes; latex expands and envelops objects; reducing the likelihood of punctures even after penetrating the tyre.
